Abstract

A rock stabilizer includes an elongated metal tube having and interior and an exterior surface with a distal end and a proximal end. The distal end is tapered and a flange is positioned adjacent the proximal end. The tube further includes a slit that runs substantially the entire length thereof. The tube is constructed so as to be capable of being positioned within a bore formed in the wall of a mine. A plurality of indentations or recesses are formed in the outer surface of the tube along the length thereof adjacent the slit so that grout or resinous material pumped into the interior of the tube can flow out of the slit and into the indentations or recesses. An expander wedge is also located within the interior of the tube adjacent the distal end and is actuatable from the proximal end of the tube after said stabilizer is installed in a bore. The wedge expands the distal end of the tube to firmly anchor the stabilizer in the bore. The expander wedge is formed of two wedges, one of which is welded to the interior of the tube and the other is capable of being moved toward the fixed wedge. The two wedges are temporarily maintained together while they are in the interior of the tube and before they are actuated.
